• Find References: Find all template usages of an hx_request
• Diagnostics: Warnings for undefined hx_request names
• Hover Information: View details about an hx_request on hover

Installation

Install via pip:

pip install hx-requests-lsp

Verify installation:

hx-requests-lsp --help

Quick Start

VS Code Setup

The easiest way to use this LSP is through the VS Code extension, which bundles the server:

1. Install the hx-requests-lsp VS Code extension from the Marketplace
2. The extension includes a bundled copy of the server - no separate installation needed
3. Open a Django project with hx-requests to start using LSP features

Alternatively, if you want to use your own installation of the server:

1. Install this package: pip install hx-requests-lsp
2. Install the VS Code extension
3. The extension will automatically detect the server in your environment

Configuration

If the extension can't find the server automatically, add to your VS Code .vscode/settings.json:

{
  "hxRequestsLsp.serverPath": "/path/to/venv/bin/hx-requests-lsp"
}

Usage

Once installed, the LSP provides these features in your editor:

Feature	How to Use
Go to Definition	F12 or Ctrl+Click on an hx_request name in a template
Find References	Shift+F12 or right-click → "Find All References"
Hover Info	Hover over an hx_request name
Autocomplete	Type {% hx_get or {% hx_post in a template (quotes optional)
Diagnostics	Undefined hx_request names show warnings

Supported Patterns

Python (definitions)

from hx_requests.hx_requests import BaseHxRequest, ModalHxRequest

class MyRequest(BaseHxRequest):
    name = "my_request"  # This name is indexed
    GET_template = "partials/my.html"

Templates (usages)

{% load hx_tags %}

<!-- hx_post with name as first argument -->
<button {% hx_post 'my_request' object=item %}>Click</button>

<!-- hx_get -->
<div {% hx_get 'another_request' %}>Load</div>

<!-- hx_vals with hx_request_name keyword -->
<div {% hx_vals hx_request_name='my_request' title='Modal' %}>Open</div>

Requirements

• Python 3.11+
• pygls >= 1.3.0 (Python Language Server library)
• lsprotocol >= 2023.0.0

Editor Support

VS Code

Use the official extension (recommended - includes bundled server)

Other Editors (Neovim, Emacs, etc.)

This LSP server works with any editor that supports the Language Server Protocol. Install via pip and configure your editor to use the hx-requests-lsp command.

Example for Neovim with nvim-lspconfig:

require'lspconfig'.hx_requests_lsp.setup{
  cmd = {"hx-requests-lsp", "--stdio"},
  filetypes = {"html", "htmldjango", "python"},
  root_dir = require'lspconfig'.util.root_pattern("manage.py", ".git")
}

Development

Setup

# Clone the repository
git clone https://github.com/jordannpenn/hx-requests-lsp
cd hx-requests-lsp

# Install dependencies
pip install -e ".[dev]"

Running Tests

pytest

Testing the Server Manually

# Test that the server responds to LSP initialize
msg='{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"processId":null,"rootUri":"file:///app","capabilities":{}}}'
printf "Content-Length: ${#msg}\r\n\r\n${msg}" | hx-requests-lsp --stdio

Troubleshooting

Server not found

1. Verify it's installed: which hx-requests-lsp
2. Check the path matches your editor's serverPath setting
3. Make sure you're in the correct virtualenv

Extension shows "Activating" forever

1. Check Developer Tools console: Ctrl+Shift+P → "Developer: Toggle Developer Tools" → Console tab
2. Look for errors mentioning "hx-requests"

No autocompletion or diagnostics

1. Ensure your template files are properly recognized by your editor
2. Restart your editor to reload the extension
3. Check that hx_request classes have a name attribute
